Specification of Letters Patent.

Patented Mar. 22, 1910.

Application filed July 2, 1909. vSerial No. 505,631.

To all whom it may concern:

Be it known that I, HARRY A. SHniLDs, a citizen of the United States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Cloth-Filing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in -cloth piling` machines, and more particularly to cutters adapted to such machines having a reciprocating carriage, and its object is to provide a cutter adapted to sever the fabric when the latter is in motion, to provide an improved cutter adapted to sever the fabric at the ends of the pile; to provide automatic means for operating the cutter and adjustable for various lengths of fabric, and to provide the device with various new and useful features, hereinafter more fully described and particularly pointed out in the claims.

My invention consists essentially of relatively Xed and movable shearing blades mounted on the carriage of the machine; mechanism on the carriage adapted to loperate the movable blade, and an adjustable member on the machine engaged by said operating means, and in various features of combination and arrangement, as will more fully appear by reference to the accompanying drawings, in which:

Figure 1 is an elevation, partly in section, of a device embodying my invention mounted on the carriage of a cloth piling machine; Fig` 2 a transverse section of the same on the line 2#2 of Fig. 1; Fig. 3 a detail of the cutting mechanism proper, shown in inverted plan View; Fig. t a detail in elevation of the roller gearing; Fig. 5 a detail showing the scales for adjusting the stop to operate the reversing mechanism of the car riage and the wedge to operate the cutter; Fig. 6 a transverse section on the line 66 of Fig. 5; and, Fig. 7 a perspective detail of a portion of the cutter operating mechanism.

Like numerals refer to like parts in all of the figures.

1 represents a portion of the frame of a cloth piling machine; 1 the frame of the reciprocating carriage; 2 a gear engaged by a pinion 6, said gear and pinion mounted on the carriage and driven by the driving shaft 5, on which shaft the pinion is splined and slidable.

3 is the lever adapted to reverse the motion of the carriage (the reversing mechanism being only partially shown, and comprising no part of my present invention).

4 is an adjustable stop engaged by the lever 3 to operate the reversing mechanism to reverse the movement of the carriage at each end of the stroke.

7 are the main feed rollers mounted on the carriage, and S a pair of auxiliary feed rollers below the same, and spaced apart therefrom. These rollers deposit the fabric 13 upon a suitable table 9 beneath the rollers. Mounted on the carriage, between the upper rollers 7 and the lower rollers 8, is a lixed shearing blade 1land a co-acting movable shearing blade 15, normally located at the respective sides of the fabric, where it extends between the upper and lower rollers.

The movable blade 15 is mounted on a slide 16 and normally retracted clear of the fabric by springs 17. When the fabric is to be severed, this slide and blade 15 are given a sudden movement across the path of the fabric and are returned again quickly, by the springs 17.

18 is a sliding bar movable transversely of the carriage and mounted thereon. On this bar are lugs 19 near the respective ends thereof, which lugs engage one arm of bell crank levers 20, the other arm of the same engaging and moving the blade 15 toward the blade 14 to shear the fabric. These levers 2O are normally held in place by springs 33. This slide is provided with an arm 27 in which is a longitudinally movable rod 21, slidable in a lug 32 on the frame of the carriage. On this rod, and engaging the arm 27 is a spring 31 engaging the lug 32 to return the slide to normal position, as shown in the drawings. Opposite this spring 31 is a heavier spring 29, engaging the arm 27 at one end and a collar 30, fixed on the rod 21, and having an inclined end to engage and release a latch 26, which engages the arm 27, and holds the parts in normal position, until released by thecollar as hereafter described.

In the end of the rod 21 is a roller 28, which traverses close to the frame 1 of the machine, on which frame is mounted an adjustable wedge 22 engaged by the roller to move the rod longitudinally and compress j the spring 29. This wedge is adjustable l longitudinally of the frame 1 by means of a binding bolt 23 extending therethrough, and adjustable in a slot 24 in the frame. On each wedge 22 is an index 25, and a scale 1c is on the frame to indicate proper adjustment of the wedge. On the stop 1 is also an index 4, and a scale 1b is on the frame to indicate adjustment of this stop to reverse the movement of the carriage, these two adj ustments being such that the fabric will be cut off the same length as the traverse of the carriage when the index of each is adjusted to the same number on the respective scales.

In operation, as the carriage reciprocates, the fabric 13 is fed downward by the rollers 7 and 8, and held tensioned therebetween. As the carriage approaches the end of the stroke and at a proper distance therefrom, the wedge 22 is engaged by the roller 28, and the rod 21 moved longitudinally, compressing the spring 29, and releasing the latch 26 by engagement of the collar 30 therewith. This' permits the spring 29 to suddenly move the bar 18 longitudinally, and the lugs thereon engaging the levers 20, move the blade 15 across the path ofthe fabric and sever the same by co-action of the blades 14 and 1.5 in the manner of shears. The stroke of the bar 18 is such that the lugs 19 will slip off the ends of the levers 2O and pass thevsame, thus releasing the movable blade, which is immediately returned to place by the action of the springs 17. The roller 28 rides upon the wedge 22 until the carriage movement is revers-ed, and as it runs back down the incline of the wedge, the spring 31 restores the parts to the position shown in the drawings, the lugs 19 passing the ends of the levers 20 on the return stroke, and said levers are restored to a position by the springs 33, whereupon at the other end of the stroke, the fabric is again severed in like manner by a corresponding wedge 22 and repetition of the same operation.

By arranging the relative position of the scales 1b and 1C, the point where the fabric is severed by the blades, will reach the end of the pile of fabric at the same time that the motion of 'the carriage is reversed.
